Notwithstanding any other provision of this Agreement, all fractional shares of Parent Common Stock that a Holder of MLP Common Units would otherwise be entitled to receive as Merger Consideration (after taking into account all MLP Common Units held by such Holder) will be aggregated and then, if a fractional share of Parent Common Stock results from that aggregation, be rounded up to the nearest whole share of Parent Common Stock (and, for the avoidance of doubt, no Person that is not a record holder of MLP Common Units or a DTC Participant will be entitled hereunder to have any fractional shares of Parent Common Stock rounded up, and none of Parent, AAI or the Surviving Entity shall have any obligation pursuant to this sentence with respect to any Person that is not a record holder of MLP

Common Units or a DTC Participant) and any such additional Parent Common Stock shall become part of the Merger Consideration.

(f)    Certain Adjustments. If between the Execution Date and the Effective Time, whether or not permitted pursuant to the terms of this Agreement, the number of outstanding MLP Common Units or shares of Parent Common Stock shall be increased, decreased or changed into a different number of units, shares or other securities (including any different class or series of securities) by reason of any dividend or distribution payable in, or an issuance of, partnership interests, voting securities, equity interests or Rights, or by reason of any subdivision, reclassification, split, split-up, combination, merger, consolidation, reorganization, exchange or other similar transaction, or any such transaction shall be authorized, declared or agreed upon with a record date at or prior to the Effective Time, then the Merger Consideration, and any other similarly dependent items shall be appropriately adjusted to reflect fully the effect of such transaction and to provide to Parent, MLP, Merger Sub and the Holders of MLP Restricted Unit Awards and MLP Public Units the same economic effect as contemplated by this Agreement prior to such event, and thereafter, all references in this Agreement to the Merger Consideration, and any other similarly dependent items shall be references to the Merger Consideration, and any other similarly dependent items, as so adjusted; provided, however, that nothing in this Section 2.1(f) shall be deemed to permit or authorize any party hereto to effect any such dividend or distribution payable in equity securities or Rights, subdivision, reclassification, split, split-up, combination, merger, consolidation, reorganization, exchange or other similar transaction, or the authorization, declaration or agreement to do such transaction that it is not otherwise authorized or permitted to be undertaken pursuant to this Agreement.

Section 2.2    Exchange of MLP Public Units.

(a)    Exchange Agent. Prior to the mailing of the Consent Statement/Prospectus, Parent shall appoint American Stock Transfer & Trust Company, LLC to act as exchange agent (the “Exchange Agent”) for the payment of the Merger Consideration and any dividends and other distributions pursuant to Section 2.2(c). At or prior to the Closing, Parent shall (i) reserve with the Exchange Agent the shares of Parent Common Stock to be issued pursuant to Section 2.1(c)(i), and (ii) authorize the Exchange Agent to exchange shares of Parent Common Stock in accordance with this Section 2.2. Parent shall, from time to time, deposit with the Exchange Agent any additional cash or other consideration as and when necessary to pay any dividends and other distributions pursuant to Section 2.2(c) (and shall authorize the Exchange Agent to pay out the same). Such Parent Common Stock and any cash or other consideration deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.” Parent shall pay all costs and fees of the Exchange Agent and all expenses associated with the exchange process. Any shares of Parent Common Stock and any other funds deposited with the Exchange Agent shall be returned to Parent after the earlier to occur of (x) payment in full of all amounts due to the Holders of MLP Public Units under this Article II and (y) the expiration of the period specified in Section 2.2(e).

(b)    Exchange Procedures. Promptly after the Effective Time, Parent shall, or shall cause the Exchange Agent to, mail to each Holder, as of the Effective Time, of MLP Public Units whose MLP Public Units were converted into the right to receive the Merger Consideration

a form of letter of transmittal (the “Letter of Transmittal”) (which shall specify that delivery shall be effected, and risk of loss and title to the MLP Certificates shall pass, only upon proper delivery of the MLP Certificates (or lost certificate affidavit as contemplated by this Section 2.2(b)) to the Exchange Agent or, in the case of Book-Entry MLP Common Units, upon adherence to the procedures set forth in the Letter of Transmittal, and which shall be in customary form and have such other reasonable provisions as Parent and MLP may agree prior to the Effective Time) and instructions for effecting the Surrender of such MLP Certificates (or lost certificate affidavit as contemplated by this Section 2.2(b)) or Book-Entry MLP Common Units in exchange for, as applicable, whole shares of Parent Common Stock and any dividends or distributions payable pursuant to Section 2.2(c). Subject to Section 2.2(c), upon Surrender to the Exchange Agent of such MLP Certificates (or lost certificate affidavit as contemplated by this Section 2.2(b)) or Book-Entry MLP Common Units, together with such properly completed and duly executed Letter of Transmittal and such other documents as may reasonably be required by the Exchange Agent, the Holder of an MLP Certificate (or lost certificate affidavit as contemplated by this Section 2.2(b)) or Book-Entry MLP Common Units shall be entitled to receive in exchange therefor, as applicable, (i) that number of whole shares of Parent Common Stock (which shall be in uncertificated book-entry form unless a physical certificate is requested) to which such Holder is entitled pursuant to Section 2.1(c)(i) and (ii) any dividends or distributions payable pursuant to Section 2.2(c) to which such Holder is entitled. The instructions for effecting the Surrender of MLP Certificates shall set forth procedures that must be taken by the Holder of any MLP Certificate that has been lost, destroyed or stolen; it shall be a condition to the right of such Holder to receive the Merger Consideration and any distributions payable pursuant to Section 2.2(c) that the Exchange Agent shall have received, along with the Letter of Transmittal, a duly executed lost certificate affidavit, including an agreement to indemnify Parent for losses suffered by Parent because of such lost certificate, in customary form, signed exactly as the name or names of the registered Holder or Holders of MLP Public Units appeared on the books of MLP immediately prior to the Effective Time, together with a customary bond and such other documents, in each case, as Parent may reasonably require in connection therewith. After the Effective Time, there shall be no further transfer on the records of MLP or its transfer agent of MLP Certificates or Book-Entry MLP Common Units (provided, however, that the foregoing shall not restrict the transfer of any MLP Partnership Interest other than the MLP Public Units after the Effective Time); and if such MLP Certificates or Book-Entry MLP Common Units are presented to MLP or its transfer agent for transfer, they shall be canceled against delivery of the appropriate Merger Consideration and any dividends and other distributions payable pursuant to Section 2.2(c) as hereinabove provided. Until Surrendered as contemplated by this Section 2.2(b), each MLP Certificate or Book-Entry MLP Common Unit in respect of MLP Public Units shall be deemed at any time after the Effective Time to represent only the right to receive upon such Surrender the appropriate Merger Consideration, together with any dividends and other distributions payable pursuant to Section 2.2(c) or (d). No interest will be paid or will accrue on any dividends and other distributions payable pursuant to Section 2.2(c) or (d).

(c)    Dividends and Distributions with Respect to Unexchanged MLP Public Units. No dividends or other distributions with respect to shares of Parent Common Stock issued in the Merger with a record date after the Effective Time shall be paid to the Holder of any MLP Certificate or Book-Entry MLP Common Units not Surrendered with respect to such shares of Parent Common Stock issuable in respect thereof until the Surrender of such MLP Certificate or

Book-Entry MLP Common Units in accordance with this Section 2.2. Subject to the effect of applicable Laws, Parent shall pay, or cause the Exchange Agent to pay, to the Holder of each MLP Certificate or Book-Entry MLP Common Units, without interest, (i) at the time of Surrender of such MLP Certificate or Book-Entry MLP Common Units, the amount of dividends or other distributions previously paid with respect to the whole shares of Parent Common Stock issuable with respect to such MLP Certificate or Book-Entry MLP Common Units that have a record date after the Effective Time and a payment date on or prior to the time of Surrender and (ii) at the appropriate payment date, the amount of dividends and distributions payable with respect to such whole shares of Parent Common Stock with a record date after the Effective Time and prior to such Surrender and a payment date subsequent to such Surrender.

(d)    No Further Ownership Rights in MLP Public Units. All Merger Consideration issued upon the Surrender for exchange of MLP Certificates or Book-Entry MLP Common Units in accordance with the terms of this Article II shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the MLP Public Units heretofore represented by such MLP Certificates or Book-Entry MLP Common Units (including all rights to common units arrearages), subject, however, to Parent’s obligation, with respect to MLP Public Units outstanding immediately prior to the Effective Time, to pay any distributions with a record date prior to the Effective Time that may have been declared or made by MLP on such MLP Public Units in accordance with the terms of this Agreement on or prior to the Effective Time and that remain unpaid at the Closing Date.

(e)    Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the Holders of the MLP Certificates or Book-Entry MLP Common Units for 18 months after the Closing Date shall be delivered to Parent, upon demand, and any Holders of the MLP Certificates or Book-Entry MLP Common Units who have not theretofore complied with this Section 2.2 shall thereafter look only to Parent and only as general creditors thereof for payment of their claim for the Merger Consideration and any distributions with respect to MLP Common Units or shares of Parent Common Stock to which such Holders may be entitled.

(f)    No Liability. To the extent permitted by applicable Law, none of Parent, Merger Sub, MLP, MLP General Partner or the Exchange Agent shall be liable to any Person in respect of any Merger Consideration or distribution properly delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any MLP Certificates or Book-Entry MLP Common Units shall not have been Surrendered immediately prior to such date on which any Merger Consideration or any distributions with respect to MLP Common Units or shares of Parent Common Stock in respect of such MLP Certificate or Book-Entry MLP Common Units would escheat to or become the property of any Governmental Entity, any such units or distributions in respect of such MLP Certificates or Book-Entry MLP Common Units shall, to the extent permitted by applicable Law, become the property of Parent, free and clear of all claims or interest of any Person previously entitled thereto.

(g)    Withholding Rights. Parent, Merger Sub and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement, without duplication, such amounts, which may include shares of Parent Common Stock, as Parent,

Merger Sub or the Exchange Agent reasonably deems to be required to deduct and withhold with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or foreign Tax Law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity by Parent, Merger Sub or the Exchange Agent, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made by Parent, Merger Sub or the Exchange Agent, as the case may be.

(h)    No Dissenters’ Rights. No dissenters’ or appraisal rights shall be available with respect to the Merger or the other transactions contemplated by this Agreement.

Section 2.3    Treatment of MLP Restricted Unit Awards.

(a)    At the Effective Time, each MLP Restricted Unit Award that is not vested and does not vest in accordance with its terms (as set forth in an applicable award agreement) as a result of the transactions contemplated by this Agreement and that is outstanding as of immediately prior to the Effective Time shall become fully vested and shall be converted into the right to receive a number of shares of Parent Common Stock equal to the number of MLP Common Units subject to each such MLP Restricted Unit Award immediately prior to the Effective Time multiplied by the Merger Consideration (rounded up to the next whole share) as soon as practicable after the Effective Date, along with any corresponding accrued but unpaid DERs (as defined in the MLP Long-Term Incentive Plan) with respect to any MLP Restricted Unit Awards.

(b)    Prior to the Effective Time, MLP and MLP General Partner shall take all action necessary to effectuate the provisions of this Section 2.3.  MLP and MLP General Partner shall ensure that, as of immediately following the Effective Time, no holder of an MLP Restricted Unit Award or participant in the MLP Long-Term Incentive Plan shall have any rights thereunder to acquire, or other rights in respect of, the equity of MLP, the Surviving Entity or any of the MLP Subsidiaries.

Except (i) as set forth in a section of the MLP Disclosure Letter corresponding to the applicable section of this Article III to which such disclosure applies (provided that (1) any information set forth in one section of the MLP Disclosure Letter shall be deemed to qualify each other section hereof to which its relevance is reasonably apparent on its face and (2) the mere inclusion of an item as an exception to a representation or warranty shall not be deemed an admission that such item represents a material exception or material fact, event or circumstance or that such item has had, or is reasonably likely to have, a MLP Material Adverse Effect) or (ii) as disclosed in the MLP SEC Reports (excluding any disclosures set forth in such MLP SEC Report under the heading “Risk Factors,” in any section related to forward-looking statements or any other disclosures included therein to the extent they are solely predictive in nature) filed on or after January 1, 2015 and prior to the Execution Date (without giving effect to any MLP SEC Report or any amendment to any MLP SEC Report in each case filed on or after the Execution Date), MLP and, with respect

to itself where provided for in this Article III, the MLP General Partner each hereby represents and warrants to the Parent Parties that:

without the prior approval of Parent and MLP Conflicts Committee, which approval shall not be unreasonably withheld, delayed or conditioned.

Section 5.6    Expenses. Subject to Sections 7.5 and 7.7, whether or not the Merger is consummated, all costs and expenses incurred in connection with this Agreement, including legal fees, accounting fees, financial advisory fees and other professional and non-professional fees and expenses, shall be paid by the party hereto incurring such expenses, except that Parent and MLP shall each pay for one-half of (a) any filing fees with respect to the Registration Statement and the Consent Statement/Prospectus and (b) the costs of printing and mailing of the Consent Statement/Prospectus; provided that, (i) if this Agreement is terminated by MLP pursuant to Section 7.3, Parent shall bear all of the costs and expenses of all parties incurred in connection with this Agreement and (ii) if this Agreement is terminated by Parent pursuant to Section 7.4, MLP shall bear all of the costs and expenses of all parties incurred in connection with this Agreement.

Section 5.8    Tax Matters. For U.S. federal income tax purposes (and for purposes of any applicable state, local or foreign Tax that follows the U.S. federal income tax treatment), the parties shall treat the Merger (a) with respect to the Holders of MLP Public Units, as a taxable sale of such MLP Common Units to DEI and (b) with respect to DEI, as a purchase of MLP Public Units from the Holders of such MLP Common Units. The Merger Consideration payable to the Holders of MLP Public Units shall be deemed to be (i) transferred from Parent to DEI in a tax free transaction pursuant to Section 351 of the Code, and (ii) immediately thereafter transferred from DEI to the Holders of MLP Public Units in accordance with the terms of this Agreement. The parties further agree that, pursuant to Treasury Regulation Sections 1.1032-3, the deemed transfer of the Merger Consideration from DEI to the Holders of MLP Public Units does not trigger the recognition of gain by DEI for U.S. federal income tax purposes, and the basis of Parent in stock of DEI shall be increased by the value of the Merger Consideration. The parties will prepare and file all Tax Returns consistent with the foregoing and will not take any inconsistent position on any Tax Return, or during the course of any audit, litigation or other proceeding with respect to Taxes, except as otherwise required by applicable Law following a final determination by a court of competent jurisdiction or other administrative settlement with or final administrative decision by the relevant Governmental Entity.

(b)    For a period of six years after the Effective Time, Parent shall maintain officers’ and directors’ liability insurance covering each MLP D&O Indemnified Party who is or at any time prior to the Effective Time was covered by the existing officers’ and directors’ liability insurance applicable to the MLP Group Entities (“D&O Insurance”) with respect to acts or omissions, or alleged acts or omissions, occurring or allegedly occurring on or after July 1, 2017 and prior to the Effective Time (whether claims, actions or other Proceedings relating thereto are commenced, asserted or claimed before or after the Effective Time); provided, however, that Parent shall not be required to pay an annual premium for the D&O Insurance for the MLP D&O Indemnified Parties in excess of 300% of the current annual premium currently paid by the MLP Group Entities for such insurance. In addition, Parent shall maintain in effect the six-year “tail” policy obtained in connection with Alon USA Energy, Inc.’s merger with and into Astro Mergerco, Inc. on June 30, 2017. Parent shall have the right to cause such coverage to be provided under (i) Parent’s corporate officers’ and directors’ liability insurance program or (ii) the applicable D&O Insurance by obtaining a six-year “tail” policy on terms and conditions no less advantageous to the MLP D&O Indemnified Parties than the existing D&O Insurance, and, in either such case, such coverage shall satisfy the provisions of this Section 5.9.

(c)    The provisions of this Section 5.9 shall survive the consummation of the Merger and the other transactions contemplated by this Agreement for a period of six years and expressly are intended to benefit each of the MLP D&O Indemnified Parties and are enforceable thereby; provided, however, that in the event that any claim or claims for indemnification or advancement set forth in this Section 5.9 are asserted or made within such six-year period, all rights to indemnification and advancement in respect of any such claim or claims shall continue until disposition of all such claims. The rights of any MLP D&O Indemnified Party under this Section 5.9 shall be in addition to any other rights such MLP D&O Indemnified Party may have under the Governing Documents of any MLP Group Entity or applicable Law.

(d)    In the event Parent or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either such case, Parent shall cause proper provision to be made so that its

successors and assigns, as the case may be, shall assume the obligations set forth in this Section 5.9; provided, that no such assumption shall release Parent from its obligations under this Section 5.9.

Section 5.10    Dividends and Distributions. After the Execution Date until the Effective Time, each of Parent and MLP shall endeavor to coordinate with the other regarding the declaration of any dividends or distributions in respect of Parent Common Stock and MLP Common Units and the record dates and payment dates relating thereto, it being the intention of the parties that Holders of MLP Common Units shall receive, for any quarter, either (i) distributions in respect of MLP Common Units or (ii) dividends in respect of Parent Common Stock that they receive in exchange therefor in the Merger.

Section 7.7    Enforcement of this Agreement. The parties hereto acknowledge and agree that an award of money damages would be inadequate for any breach of this Agreement by any party and any such breach would cause the non-breaching parties irreparable harm. Accordingly, the parties hereto agree that prior to the termination of this Agreement, in the event of any breach or threatened breach of this Agreement by one of the parties, the parties will also be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance, provided such party is not in material default hereunder.

$100,000 and that this Agreement has been entered into in express reliance upon 6 Del. C. § 2708.

Each party hereto hereby irrevocably and unconditionally (i) consents and submits to the exclusive personal jurisdiction and venue of the Delaware Court of Chancery (or, solely if the Delaware Court of Chancery declines to accept jurisdiction over any matter, any federal or state court located in the State of Delaware) (the “Delaware Courts”) for any actions, suits or proceedings arising out of or relating to this Agreement or the transactions contemplated by this Agreement (and agrees not to commence any litigation relating thereto except in such courts), (ii) waives any objection to the laying of venue of any such litigation in the Delaware Courts and agrees not to plead or claim in any Delaware Court that such litigation brought therein has been brought in any inconvenient forum, (c) acknowledges and agrees that any controversy that may arise under this Agreement is likely to involve complicated and difficult issues, and therefore each such party hereby irrevocably and unconditionally waives any right such party may have to a trial by jury in respect of any litigation directly or indirectly arising or relating to this Agreement or the transactions contemplated by this Agreement, and (d) agrees to service of process upon such party in any such action or proceeding shall be effective if such process is given as a notice in accordance with Section 8.1 or in any manner prescribed by the Laws of the State of Delaware. Nothing in this Section 8.2 shall affect the right of any party to serve legal process in any other manner permitted by Law.

Section 8.3    Entire Agreement; Amendments, Consents and Waivers.

Except as expressly set forth in this Agreement (including the representations and warranties set forth in Articles III and IV), (i) the parties acknowledge and agree that neither the MLP Group Entities nor any other Person has made, and the Parent Group Entities are not relying upon, any covenant, representation or warranty, expressed or implied, as to the MLP Group Entities or as to the accuracy or completeness of any information regarding any MLP Group Entity furnished or made available to any Parent Group Entity, (ii) the parties hereto acknowledge and agree that, except as set forth in this Agreement, neither the Parent Group Entities nor any other Person has made, and the MLP Group Entities are not relying upon, any covenant, representation or warranty, expressed or implied, as to the Parent Group Entities or as to the accuracy or completeness of any information regarding any Parent Group Entity furnished or made available to any MLP Group Entity, and (iii) the MLP Parties and the Parent Parties shall not have or be subject to any liability to any Parent Group Entity or any other Person or any MLP Group Entity or any other Person, as applicable, or any other remedy in connection herewith, based upon the distribution to any Parent Group Entity or any MLP Group Entity of, or any Parent Group Entity’s or any MLP Group Entity’s use of or reliance on, any such information or any information, documents or material made available to the Parent Group Parties or MLP Group Parties, as applicable, in any “data rooms,” “virtual data rooms,” management

presentations or in any other form in expectation of, or in connection with, the transactions contemplated hereby.

(b)    Subject to compliance with applicable Law, prior to the Closing, any provision of this Agreement may be (i) consented to or waived in writing by the party benefited by the provision or (ii) amended or modified at any time by an agreement in writing by the parties hereto; provided, however, that, in addition to any other approvals required by the MLP Parties’ constituent documents or under this Agreement, the foregoing consents, waivers, amendments or modifications in clauses (i) and (ii), and any decision or determination by MLP to (x) terminate this Agreement pursuant to Section 7.2 or Section 7.3, (y) waive any conditions set forth in Article VI and proceed to Closing or (z) enforce this Agreement (including pursuant to Section 7.7), may be granted, taken, made or directed by the MLP Conflicts Committee (without the need to obtain any further approval of the MLP Board) and in all cases shall require the approval of the MLP Conflicts Committee. No amendment, supplement, modification or waiver of this Agreement shall be binding unless executed in writing by the parties hereto. The failure of a party to exercise any right or remedy shall not be deemed or constitute a waiver of such right or remedy in the future. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (regardless of whether similar), nor shall any such waiver constitute a continuing waiver unless otherwise expressly provided.

Section 8.4    Binding Effect; No Third-Party Beneficiaries; and Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Nothing in this Agreement, express or implied, is intended to confer upon any Person other than the parties hereto and their respective permitted successors and assigns, any rights, benefits or obligations hereunder, except (i) as provided in Section 5.9 and (ii) for the right of the Holders of MLP Common Units to receive the Merger Consideration after the Closing (a claim by the Holders of MLP Common Units with respect to which may not be made unless and until the Closing shall have occurred). No party hereto may assign, transfer, dispose of or otherwise alienate this Agreement or any of its rights, interests or obligations under this Agreement (whether by operation of law or otherwise). Any attempted assignment, transfer, disposition or alienation in violation of this Agreement shall be null, void and ineffective.

Section 8.5    Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of applicable Law, or public policy, all other conditions or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement are not affected in any matter materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the fullest extent possible.

Section 8.6    Counterparts. This Agreement may be executed in multiple counterparts each of which shall be deemed an original and all of which shall constitute one instrument.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be signed by their respective officers or agents hereunto duly authorized, all as of the date first written above.
